Ok, I have a friend that needs to unlock to switch to T-Mobile
iPhone 4 GSM
IOS 4.2.1 FW
Baseband 3.10.01
No SHSH
Clicked make my life easier, but I'm sure it was 4.3.1 or 4.3.2 by the time she did she just JB recently
SHe's currently JB by greenposion, can she just unlock as she has no SHSH saved...maybe ultrasnow? Or would she have to use snowbreeze & if so without SHSH is it possible, I believe if I understand right snowbreeze creates a custom ipsw that's unlocked...but I'm not sure @ all as I have never had to unlock any of my iPhone's as I have always use AT&T, sorry for my ignorance. Would someone please help me, I would like her to stay on 4.2.1 without losing JB & just be unlocked if that's possible without SHSH cuz I think u have to restore to unlock a lot of the time. Or any help to unlock successfully even if she has to update I guess but would much rather not if possible. Thanks in advance
